Tim I agree here on the western side of Europe there were fewer wideband signals compared to previous years. The worst I heard was a Ukraine call who was very wide. People are moving to AFSK/replacin

RTTY contesting when running with not many takers is when the highest long term duty cycle happens. It can get as high as 70 to 80% TX time. Otherwise it is normally around 50%. If worried about this

Using EXTFSK(64) or for that matter 2Tone FSK using bit diddling of a COM port control line is one way of making sure you get extra errors on the far ends decode and being asked to repeat. Windows is

Peter As far as I know they just use a USB to COM port adapter probably a chip from FTDI. But why spend money on a box when you can just use AFSK for a very small sum in making your own sound card to

Is that a learning moment that says: Don't buy an ICOM? 73 David G3YYD Agreed Joe! The Icom IC7300 is like this. I wish radio manufactures would allow AFSK when in RTTY mode with a simple menu change

But never use RX based twin peak filtering with 2Tone. May well sound better to the human ear but it will be worse for the decoder. 2Tone uses optimised filtering and anything that narrow in the RX w

Correct. Only 2Tone can know when FSK transmission starts and end so has to control PTT. Maybe I should remove the no option. Not being a FSK operator had not seen that one. PTT on audio input is opt

In N1MM+ whatever is in the main Di window is the TX software. The additional RX windows are RX only. So to use 2Tone for TX in N1MM+ need to make it the main Di window software. 73 David G3YYD Thank
